Render Map Dialog Updates

[lightcube]

The Render Map Dialog needs to be brought into the modern age:

• Default Render Size should not be 240. It should be 512 (or 1024).
• Should include a dropdown or buttons for common sizes (256,512,1024,2048, etc)
• Should include a ratio lock: when on, changing one dimension changes the other
• Presets: Allow saving current settings as preset; allow loading presets.

It would also be nice if it was possible to render map and have it automatically load into into the material editor as a new node you could immediately hook up in the material editor. It could be useful for example if you want to create a bitmap of a procedural effect for exporting into another application like a game engine or something.

And to make it faster it should also have some sort of automatic unique naming system for saving files into a folder of your choice.

Both good ideas @markus.
